Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited

CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-306

A sensitive function is reachable with no authentication at all, so anyone who finds the endpoint can use it. These are routinely discovered by automated scanning. The fix is to require and enforce authentication on every privileged path, with no exceptions left open.

Recommended fix High confidence

Apply Oracle CPU October 2023 or later. For a version upgrade path: WebLogic 12.2.1.4.0 (with Oct2023 CPU applied) or upgrade to 14.1.1.0.0 (with Oct2023 CPU applied). Oracle also released 12.2.1.4.0.0.240101 (Jan2024 CPU) and subsequent patches.

  1. Apply Oracle Critical Patch Update October 2023 (or later) which contains the fix for CVE-2023-22069. Download the patch from Oracle Support (requires Oracle account).
  2. For WebLogic Server 12.2.1.4.0: Apply patch 35771818 (or latest CPU patch) which addresses this vulnerability.
  3. For WebLogic Server 14.1.1.0.0: Apply patch 35771817 (or latest CPU patch) which addresses this vulnerability.
  4. Alternatively, as a defense-in-depth measure, disable T3 and IIOP protocols if not required by setting appropriate network access controls or disabling these protocols in the WebLogic Server administration console.
  5. After applying the patch, restart all WebLogic Server instances to ensure the fix takes effect.
  6. Verify the patch was applied successfully by checking the WebLogic Server version/patch inventory.
Caveat Patches applied via Oracle OPatch typically have minimal impact; however, always test CPU patches in a non-production environment before deploying to production to ensure compatibility with custom applications.
